murmsrinn LOCK AND RELEASE DEVICE. h

Application filed May 1,

This invention relates to turnstiles, and, moreparticularly, to devices for locking the same against operation and releasing mecha nisin for the lock devices. 7

. The object of the invention is to provide a simple and effective turnstile lock and release mechanism. 7

A further object is to provide a turnstile lock and release mechanism which is electrically controlled.

Afurther objectis to provide an electrically controlled lock releasing mechanism, the circuit of which, with full operating current stren th, is closed momentarily by a de- POSlt-Qd'COlIl, and. wherein the initial operation closes anauxiliary circuit and cutsout the coin control, the auxiliary circuit con-" taining resistance.

' 'A further object is "to provide a lock-and release mechanism which can be economically constructed and easily installed, and

which is strong and rugged.

Other objects will appear more fully here inafter. r

The invention consists substantiallygin the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawing and finally pointed out in the appended claims. I The single View of the drawing shows a lock and release mechanism for turnstiles embodying our invention, parts broken off, parts in elevation, parts in'section, and parts in diagram. v

The present invention relates more particularly to the stop dog and pawl and the actuating mechanism therefor, the main purpose being to dispense with the electro-pneumatic operating devices, and to greatly simplify and cheapen the structure, operation, and arrangement of these parts.

Reference numeral 5 designates the turnstile shaft upon which is mounted the ratchet wheel 6, having the peripheral teeth 7, and the groups of teeth8 separated by'the stop shoulders 9. A pawl10 cooperates with the peripheral teeth 7 of the ratchet wheel, and a dog 11 cooperates with the teeth 8 and stop shoulders 9. Atension spring 12 normally presses the stop dog 11 into engagement against a stop shoulder of theratehet wheel, and a finger 13'holds the pawl 10 out of engagement with the ratchet teeth 7. V

The parts so far described correspond 1926. senarim'ioaa'ia eration as the corresponding parts in our Patent $81,578,660, patented March 30,1926, for turnstile mechanism with elect-ro-pneu'- matic actuating devices In place of theelectro-pneumatic devices for actuating the stop dog, we propose, in

our present invention, to employ ama net; coil 14', the core 15 of which is carried by an armature or pole piece 16, pivotally mounted at one side ofthe magnet coil 1d as at17.

A bracket 18 carried of an arm'20, connected to the stop dogll or carr ed by the stud '21 .on which said stop isv mounted; If desired, and as shown, a

friction roller22 carried by bracket 18, takes p by the pivoted *pole' p1ece16 works against the curved surface 19 the parts above describedoccupy thetposi- 1 tions thereof'as shown in the drawing, the dog 11 being pressed by the spring 12 into abutment against ashoulder 9 onthe ratchet wheel, the pin 7 13 holding pawl 10 out of engagement with the peripheral teeth 7, and the pivoted pole piece 16 being heldin raised position by the curved "arm 20 which is also influenced to this normal position by the spring 12. .Ifrequired, however, an'auxiliary spring 23 may act onthe pole piece 16 to raise the saniew The turnstileis now in condition for unobstructed exit operation but is" retained by the dog 11 against entrance operation hen the circuit of magnet coil 14; is closed-and said magnet coil becomes energized, the core 15 and the pole piece are attractedthereby, the latter rocking, down-- wardly', thereby causing the bracket 18, or the roller 22 thereon, to move along the curved surface 19 of arm 20, thereby rocking the'latter in a direction to withdraw the dogfll from engagement with a stop shoulder 9, and also releasing the pawl 10. This places the turnstile in condition for entrance operation but is prevented by pawl 10 from exitoperation in reverse direction.

At'its free end the armature or pole piece 16, maybe formed or provided with an angle portion 24 which actsas a pole piece in cooperation with'a pole member 25 to addqan attractive force torock the armature 16 in dog withdrawing direction, and to retain the same retracted as long as the'circuit of magnet coil 14 remains closed.

'We have indicated a conventional coin controlled circuit arrangement for the magnet coil 14,

magnet coil 14 remains effectively ener-' gized, the turnstile remains unlocked andlis free for entrance operation without additional coin deposits, .but is locked against reverse exit operation. in case, for any reason,-,a deposited coin SllOillil bECOHlQ lodged and wedged in bridging relation with respect to the contacts 27, 28, the circuit of the magnet coil might remain closed through the coin. Moreover, so long as the co n controlled circuit remains closed, current of full operating strength flows through the .itis apparent that magnet coil circuit, thereby resulting in waste of current. These are practical objections which it is among the special purposes of our present invention to avoid, and we therefore arrange a switch device in the coin controlled circuit of the magnet coil 14 and utilize the rocking movement of the armature 16 to control the switch device. In the illustrative arrangement shown, a contact disk 29 is carried by a stem 30, and is arranged to workbetween the pairs of contacts 31, 32, and 33, 34, to bridge the members of said pairs. Normally a spring 35 maintains the disk 29 in bridging relation with respect to the contacts 31, 32, so that when a deposited coin bridges thecontacts 27, 28, the circuit of the magnet coil 14 is closed through the contacts 31, 32, and disk 29. The closing of this circuit causes the armature 16 to rock, whereupon a lug 36 carried by said armature engages the end of stem 30 and shifts the disk 29 out of bridging relation with respect to contacts 31, 32, and into bridging relation with respect to contacts 33, 34. The circuit which includes these contacts includes also resistances 37, 38,-as well as the magnet coil, 14. Of course,

short circuit the magnet coil 14. For instance, if a coin 26 is de posited it bridges contacts 27, 28, thereby closing the circuit of magnet coil 14, from trolley, or other source, through a, b, 32, 29, 31, c, magnet coil, (Z, 7, 27, coin 26, 28, g, to ground or return. The closing of this circuit is only momentary since resulting energization of the magnet coil effects a shifting of contact disk '29 out of contact with 31, 32 and into contact with 33, 34. This opens the circuit which includes the coin, and which received the full operating strength of the current, and closes a circuit fromtrolley through a, h, 37, 38, m, 40, 41, 42, a, magnet coil, 0, 33, 29, 34, to ground or return. This circuit is independent of that containing the coin contacts 27, 28, and therefore any jammingor lodgment of the coin will not affect the supply of current in the employed to entirely the contacts 33, 34 may be solenoid circuit. Moreover, the circuit through the contacts 33, 34, also includes re sistance, as indicated at 37, 38, thereby cutting down the consumption of current when the circuit of the magnet coil is closed through the contacts 33, 34, instead of through the contacts 31, 32, the coin and contacts 27, 28. The next step in the operation is to open the circuit through the magnet coil, so that the turnstile may be restored to condition for exit operation and locked against entrance operation until the deposit of another coin. This result is attained by associating the auxiliary circuit of the magnet coil with the operation of the turnstile. This is accomplished by employing the contacts 40 and 42 which cooperate with a conducting segment 41 mounted on a block 43 carried by the turnstile shaft 5. When this shaft is in position for entrance operation the segment 41 bridges the contacts 40, 42, but when the turnstile shaft is displaced, as by a personpassing through in entrance direction,the segment 41 is carried out of bridging relation with respect to contacts 40, 42, thereby opening the magnet coil circuit therethrough. This causes the magnet coil to become ole-energized and hence the armature 16 is restored to its raised position and the disk 29 is raised from contacts 33, 34, into contact with 31, 32, thereby restoring all parts to condition for another cycle of operation.
